Saying Goodbye to 3M and Tesa Fiberglass Tapes: How You-San is Changing the Game

Due to historical differences in industrial development, the global adhesive tape market has been dominated by large companies such as 3M and Tesa, primarily based in the US. Currently, in the field of fiberglass tape, foreign brands such as 3M and Tesa have a higher market share, while domestic brands have a lower market share. You-San aims to provide an economical and technically superior alternative to 3M and Tesa products with our complete research and development team and series of fiberglass tape products, including unidirectional fiberglass tape (striped fiberglass tape), bidirectional fiberglass tape (grid fiberglass tape), and double-sided fiberglass tape. All of our products are independently researched and developed and can replace foreign brand fiber tape with a price advantage to achieve domestic production of tape.

Our team of experts has developed fiber tapes made from the highest quality materials and the latest manufacturing techniques to deliver superior performance and durability. By utilizing advanced adhesives and special coatings, our tapes possess high tensile strength and superior bonding properties, outperforming many of the products currently available in the market. Furthermore, the best part of our fiber tape is our price. Our state-of-the-art technology and manufacturing processes allow us to offer our products at a much more competitive price point than 3M and Tesa's products. This means that you do not have to compromise on quality and performance, while saving a significant amount of money in the process.

Let's take a look at what fiberglass tape is. fiberglass tape is a specialty tape made of glass fiber composite PET/PP film substrate. It is also called fiber glass tape or filament tape. Its main features include high tensile strength, excellent wear resistance, strong load-bearing capacity, high peel strength, and no residue.

fiberglass tape is generally composed of release liner, substrate, composite adhesive, reinforcing fiber, pressure-sensitive adhesive, etc. (as shown in Figure 1 below). Commonly used substrates include PET film, PVC film, BOPP film, and various papers that have been surface treated.

Fiber-reinforced adhesive tape can be classified into three types based on its tensile strength: standard tensile strength, medium tensile strength, and high tensile strength. Their tensile strengths are as follows: standard tensile strength is 160-290N/cm, medium tensile strength is 300-450N/cm, and high tensile strength is 460-850N/cm.


The main application industries are as follows:


heavy object

temporary winding and fixation of coil materials

 temporary fixation of electrical appliances

model pasting and fixation

wire fixation

 lithium battery fixation

lithium battery binding

lithium battery assembly

Heavy duty application
